Referencing Hurricane John's mention of Valley cover bolt washers that are thicker than originals & can cause bottoming out of an intake manifold.. I believe the set I have here are like that. They weren't in original packaging and are marked NPC & 55. The washers are molded to the rubber & the upper rubber area, before the taper, is 1/4" thick. They appear too thick for under a "B" manifold. Looking at them I can't see a viable way to shorten them..Any suggetions? (and thanks John)

I cut mIne down with an x-acto type knife though the middle, separating the top from the bottom. Then I clean up the washer (removing all the rubber), and then just put the washer on the shortened bottom piece. .

Paul and Paul, I also cut them in half with a knife, but I use the "top" half of the grommet and don't worry about the locating projection. I just locate the cover where I want it and tighten bolt. They won't move then. The rear grommet doesn't need trimmed, the manifold is no where close to the rear bolt. The grommets included in today's gasket sets are actually rocker cover grommets.

Another suggestion is to shorten the bolt head. A lathe works good for this but nothing wrong with just using a grinder for doing that.
